5011 (make_binding_level): Use ggc_alloc_cleared or memset.
5012 (lookup_tag): Remove struct binding_level* parameter. All
5013 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
5014 current_binding_level->tags if asked for thislevel_only or if
5015 we might have to diagnose "struct foo; union foo;"
5016 (pushlevel): Ignore argument. Do not push another binding
5017 level on the transition from the parameters to the top level
5018 of the function body; just tweak the flags and proceed.

5020 a function body, separate the parameter list from the
5021 top-level local variables.
5022 (set_block): Do nothing.

5066 (c_print_identifier): Update to match changes to struct
5068 (poplevel): Delete #if 0 block. Make externals invisible
5069 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5070 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5071 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5072 (duplicate-decls): For real parm decl after a forward decl,
5073 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

5077 local-over-local. Clarify comments.
5078 (pushdecl): Rewritten. There is no longer a distinction
5079 between global and local symbol values; they're all
5080 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5081 DECL_EXTERNAL decls, and use any_external_decl to check
5082 against previous externals. Kill #if 0 blocks. Don't
5083 tolerate error_mark_node being NULL.

5085 Objective C (the only user) needs.
5086 (pushdecl_function_level): New function.
5087 (implicitly_declare): Create ordinary decls with
